My highschool had “coordinates”, not a uniform. But they stopped selling the shorts like a decade before I started there… So me and a bunch of buddies tracked down used pairs and started wearing them.
Next year, shorts were banned outright… So me and a bunch of buddies on the rugby team started wearing skirts, because the rules said skirts were acceptable, but didn’t specify gender. So you had a bunch of guys with hairy, hairy legs walking around in skirts we deliberately hiked up a little to show some thigh.
Shorts were allowed again in a week.
